No study has examined the role of inhaled glycopyrrolate on mucus secretion. We hypothesize that nebulized glycopyrrolate will improve bronchoscopy procedure by effectively suppressing airway mucus secretion, thereby decreasing cough, and thus improving patient comfort during bronchoscopy. In this study, we aim to compare the efficacy of nebulized glycopyrrolate versus nebulized ipratropium in suppression of cough during flexible bronchoscopy.
